Question

Stacy opens a new saving account and deposit $400 then she deposit 200 every month identify the input variable output variable initial value and rate of change

Answer 1

we are told that $400 is deposited in a bank account and that every month $200 is added. If "m" is the number of months then the total balance for a given number of months is given by:

$b=400+200m$

In this case, the input variable is the number of months "m" and the output variable is the balance "b". The initial value is $400 and the rate of change is:

$r=200\text{ dollars/month}$
